Final answer:
Without context about the game or setting called 'Yorkton', it is impossible to provide an accurate answer to what is needed to access higher districts within it.
Step-by-step explanation:
The question posed regarding what is needed to gain access to higher districts in Yorkton would seem to pertain to a game or fictional setting, rather than a real-world academic subject. Without additional context or knowledge about the specific game, narrative, or system being referred to as 'Yorkton', it is not possible to provide an accurate answer. Access requirements in games or fictional settings can vary widely, from passcodes and special keys to more fantastical means like flying vehicles or a character's special identification, such as a Gold's identification.
